Returning struct from function causes memory corruption
8 janvier 2015, par William SeemannI’m trying to return a FFmpeg AVDictionary struct from one function to another. I wrote the following two functions :
int get_p_metadata(State **ps, AVDictionary *metadata) {
printf("get_p_metadata\n");
State *state = *ps;
if (!state || !state->pFormatCtx) {
return FAILURE;
}
metadata = NULL;
av_dict_copy(&metadata, state->pFormatCtx->metadata, 0);
printf("count in get_p_metadata %d\n", metadata->count);
return SUCCESS;
}
int get_metadata(State **ps) {
printf("get_metadata\n");
AVDictionary m;
get_p_metadata(ps, &m);
printf("count in get_metadata %d\n", (&m)->count);
return SUCCESS;
}The code compiles and runs however when I call the
get_metadata
function the generated output is :count in get_p_metadata 12
count in get_metadata 2073109240Can someone explain why the value of
count
changes from 12 to a random value every time I run this code ? Why isn’t the value of 12 retained once theget_p_metadata
function returns ? How would I fix this ?UPDATE :
This solution worked (Thanks to Cornstalks for actually reading the FFmpeg documentation and
linkdd for the answer) :int get_p_metadata (State **ps, AVDictionary **metadata) {
printf("get_p_metadata\n");
State *state = *ps;
if (!state || !state->pFormatCtx) {
return FAILURE;
}
av_dict_copy(metadata, state->pFormatCtx->metadata, 0);
return SUCCESS;
}
int get_metadata(State **ps, AVDictionary *metadata) {
printf("get_metadata\n");
AVDictionary *m = NULL;
get_p_metadata (ps, &m);
printf("count in get_metadata %d\n", m->count);
return SUCCESS;
}
